Description

Power management method and terminal device

The present application claims priority to Chinese Patent Application No. 20161091381 3.9, filed on Jan. 19, 2016, the entire disclosure of which is incorporated herein by reference. In this application.

Technical field

The present invention relates to the field of computer technologies, and in particular, to a power management method and a terminal device.

Background technique

At present, after the power of the terminal device is below a certain threshold, some terminal devices, such as mobile phones, will emit an alarm tone, or will remind the user whether to perform the operation of "entering power saving mode". If the user determines to enter the power saving mode, the mobile phone closes all relevant applications under the established criteria, leaving only some of the more critical functions.

It can be seen that the current power-saving mode belongs to the after-treatment mode, that is, when the power is already low, the power consumption behavior has already occurred, and the effect on power saving is limited.

Summary of the invention

The embodiments of the present invention provide a power management method and a terminal device, which are used to prevent an ongoing service from being affected due to power saving.

In a first aspect, a method of power management is provided, the method being performed by a terminal device. The method includes the terminal device receiving a first operation, the first operation being used to invoke the first application. The terminal device queries the association relationship between the power range and the application to determine whether the first application invoked in response to the first operation is an available application associated with the power range to which the current remaining power of the terminal device belongs. When the first application is not an available application associated with the current power range to which the remaining power belongs, the terminal device does not invoke the first application.

In the embodiment of the present invention, the relationship between the power range and the application program may be set in advance, and after receiving the first operation, the terminal device determines whether the first application to be called by the first operation is The available application associated with the current battery range to which the remaining battery belongs, if not, the terminal device refuses to call the first application, that is, it can fundamentally eliminate the possibility of running more power-consuming applications. When there is sufficient time, it can be managed according to the set relationship, effectively arrange the operation of the application, and improve the endurance of the terminal equipment.

With reference to the first aspect, in a first possible implementation manner of the first aspect, before the terminal device does not invoke the first application, the terminal device outputs the first prompt information, and the terminal device receives the input operation for the first prompt information. The first prompt information is used to prompt whether to abandon the first application. Then, the terminal device does not invoke the first application, and includes: when the input operation is used to instruct to give up calling the first application, the terminal device does not invoke the first application.

The terminal device is most important to meet the needs of the user. Therefore, if the terminal device thinks that the first application should not be called, the terminal device may first query the user. If the user determines to abandon the first application, the terminal device determines not to call. The first application saves power and meets the needs of users. If the user chooses to continue to invoke the first application, the terminal device can continue to call the first application to meet the user's needs as much as possible to improve the user experience. Moreover, since the terminal device outputs the first prompt information, the user knows that the first application is not suitable for calling at present, and even if the user chooses to continue to call the first application, the user should be more restrained and not waste too much power. Or maybe choose to charge in time. That is, by outputting the first prompt information, the user can be well presented and the practicality of the terminal device can be increased.

With reference to the first aspect or the first possible implementation manner of the first aspect, in a second possible implementation manner of the first aspect, the terminal device divides the power of the terminal device into at least one power range, where the terminal device is A range of power levels is associated with at least one application to form an association. The minimum value of the power included in the at least one power range is the minimum power that the terminal device can support, and the maximum power level included in the at least one power range is the maximum power that the terminal device can support.

Because the terminal device determines whether to call the application according to the relationship between the power range and the application, the terminal device can establish an association relationship between the power range and the application in advance, so that when the application needs to be invoked, Judging directly based on the established association relationship makes the subsequent judgment process of whether the application can be called is very simple.

In conjunction with the first aspect or the first possible implementation of the first aspect or the second possible implementation of the first aspect, in a third possible implementation of the first aspect, when the first application is The terminal device invokes the first application when the current remaining power belongs to the available application associated with the power range.

If the first application is an available application associated with the current power range to which the remaining power belongs, indicating that the power of running the first application is sufficient, and the first application is callable, the terminal device directly invokes the first application. The program allows the user to use the first application normally.

With reference to the first aspect or any one of the first possible implementation manner to the third possible implementation manner of the first aspect, in a fourth possible implementation manner of the first aspect, the terminal device Determining that the remaining power of the terminal device enters the second power range from the first power range included in the association relationship. When the second application running in the terminal device is not the available application associated with the second power range, the terminal device outputs second prompt information, and the second prompt information is used to prompt whether to close the second application.

When the terminal device calls the second application, the second application may be an available application associated with the power range to which the remaining power of the terminal device belongs, and the terminal device normally invokes the second application. After the second application runs for a period of time, the power of the terminal device decreases, and the remaining power of the terminal device may enter the second power range, and the second application is not an available application associated with the second power range. At this time, the terminal device can directly stop running the second application to avoid the power consumption being too fast due to running the first application, which affects the subsequent use of the user. Alternatively, the terminal device may temporarily stop running the second application, but output the second prompt information, that is, the terminal device may first query the user, and if the user determines to abandon the second application, the terminal device determines not to call the second application. The application saves power and meets the needs of users. If the user chooses to continue to invoke the second application, the terminal device can continue to call the second application to meet the user's needs as much as possible to improve the user experience. Moreover, since the terminal device outputs the second prompt information, the user knows that the second application is not suitable for calling at present, and even if the user chooses to continue to call the second application, the user should have more Moderation, does not waste too much power, or may choose to charge in time. That is, by outputting the second hint information, the user can be well presented and the practicality of the terminal device can be increased.

In a second aspect, a method of power management is provided, the method being performed by a terminal device. The method includes the terminal device receiving a second operation, and the second operation for updating a system or an application installed in the terminal device. The terminal device determines whether the terminal device is in a charging state. When the terminal device is not in the charging state, the terminal device does not respond to the second operation.

The second operation is to update the operation of the class, and the operation of the update class is generally relatively power-consuming. If the terminal device is not in the charging state, it is likely that the power consumption of the terminal device is too fast due to the response to the second operation. Affect the subsequent use of the user. Moreover, because the operation of the update class generally lasts for a long time, if the terminal device shuts down because there is no power before the end of the response because the second operation is responded, the update is not completed, which may cause the system or the corresponding software to malfunction. Therefore, in order to avoid these problems, if the terminal device receives the operation of the update class, it may be determined whether the terminal device is in a charging state, and if the terminal device is not in the charging state, the terminal device may not respond to the second operation to avoid power consumption. many.

With reference to the second aspect, in a first possible implementation manner of the second aspect, before the terminal device does not respond to the second operation, the terminal device determines whether a difference between the remaining power of the terminal device and the amount of power required to respond to the second operation is The preset threshold is less than the preset threshold, and the preset threshold is the safe power value of the terminal device. Then, the terminal device does not respond to the second operation, and includes: when the difference between the remaining power of the terminal device and the power required to perform the second operation is less than a preset threshold, the terminal device does not respond to the second operation.

In general, for an operation of an update class, the terminal device can know in advance the amount of power required to respond to such an operation. The knowledge here is not necessarily very accurately known, just know the approximate value. After receiving an operation, of course, the user prefers to perform the operation. Therefore, if the terminal device is not in the charging state, the terminal device may further determine whether the difference between the remaining power of the terminal device and the power required to respond to the second operation is less than a preset threshold, if the remaining power of the terminal device is in response to the second operation If the difference of the required power is less than the preset threshold, it indicates that the terminal device cannot respond to the second operation normally. For example, it is likely that the abnormal shutdown is caused by responding to the second operation, and the terminal device determines to not respond to the second operation at this time to protect the terminal. device.

With reference to the first possible implementation manner of the second aspect, in a second possible implementation manner of the second aspect, the difference between the remaining power of the terminal device and the power required to perform the second operation is greater than or equal to the preset At the threshold, the terminal device responds to the second operation.

If the difference between the remaining power of the terminal device and the power required to respond to the second operation is greater than or equal to the preset threshold, it indicates that the terminal device can still respond to the second operation normally, so the terminal device can select to respond to the second operation, which is equivalent to normal.

Referring to FIG. 2, an embodiment of the present invention provides a power management method, which may be performed by the terminal device 100 in the embodiment shown in FIG. 1A or FIG. 1B.

Step 201: The terminal device 100 receives the first operation; the first operation is used to invoke the first application;

Step 202: The terminal device 100 queries the association relationship between the power range and the application to determine whether the first application invoked in response to the first operation is an available application associated with the power range to which the current remaining power of the terminal device belongs.

Step 203: When the first application is not an available application associated with the current power range to which the remaining power belongs, the terminal device 100 does not invoke the first application.

The embodiment shown in FIG. 2 is specifically described below by taking the processor 190 in the terminal device 100 as an example.

In the embodiment of the present invention, an application may also be referred to as an application (application).

The first operation may be an operation performed by the user on the terminal device 100, such as a touch operation performed by the user on the touch screen 131. Or the first operation may also be an operation performed by the terminal device 100 itself. For example, a malicious application is installed in the terminal device 100, and the malicious application may invoke the malicious application by using the first operation when the user does not operate. The program, or the malicious application, may invoke other applications by the first operation without the user's operation, so that the application runs secretly in the background of the terminal device 100, consuming power. In the following, the first operation is mainly the operation performed by the user on the terminal device 100. Referring to FIG. 3, the user operates the display unit 140 of the terminal device 100. Some display icons are displayed on the display unit 140, and each application icon corresponds to one application. The user clicks on the application icon 5, that is, the user performs the first operation, and after receiving the first operation, the terminal device 100 determines that the application corresponding to the application icon 5 needs to be invoked, for example, the first application.

The first operation requires the first application to be called. Then, the processor 190 obtains the current remaining power of the terminal device 100 provided by the power management unit 194 through the operating system, and the processor 190 queries the association relationship between the power consumption range and the application, and determines that the current remaining power of the terminal device 100 belongs to. The range of power, and whether the first application is an available application associated with the range of power to which the current remaining battery belongs. If the first app is with the current remaining battery The processor 190 can invoke the first application by responding to the first operation by the available application associated with the range of powers. And if the first application is not an available application associated with the current power range to which the remaining power belongs, the processor 190 does not invoke the first application, thereby substantially eliminating the operation of the more power-consuming application. Possibility, when the power is still sufficient, it can be managed according to the set relationship, effectively arrange the operation of the application, and improve the endurance of the terminal device.

In the above, the relationship between the power range and the application is mentioned. The following describes how to obtain the relationship.

The processor 190 of the terminal device 100 may divide the power of the terminal device 100 into at least one power range, and the minimum power included in the at least one power range is the minimum power that the terminal device 100 can support, and the at least one power range includes the largest amount of power. The value is the maximum amount of power that the terminal device 100 can support. Here, the minimum power that the terminal device 100 can support may be the actual minimum power of the terminal device 100, for example, 0%, or the alarm power of the terminal device 100. The alarm power varies according to the terminal device 100. Generally, it is 20%, and may be 15%, or 10%, etc., if the remaining power of the terminal device 100 is less than the alarm power, the terminal device 100 generally performs an alarm, and in addition, the terminal device 100 works in a state less than the alarm power. Underneath, it may not be very stable, and abnormal shutdown may occur at any time. The embodiment of the present invention does not limit the value of the minimum power that the terminal device can support. After dividing at least one power range, at least one application is associated with each of the power ranges, thus forming a relationship between the power range and the application. The association relationship may be set by the terminal device 100, for example, at the time of shipment, or the association relationship may also be set by a user who uses the terminal device 100.

See Figure 4 for an example of an association. In FIG. 4, the application 1, the application 2, the application 3, the application 4, and the application 5 installed in the terminal device 100 are exemplified by an application associated with the power consumption range, wherein the application 1, the application 2 The application 3, the application 4, and the application 5 may be all applications installed in the terminal device 100 or part of applications installed in the terminal device 100. The terminal device 100 divides the power of the terminal device 100 into five power ranges according to five power thresholds, and the five power thresholds are respectively N1 and N2. N3, N4, and N5. Among them, the power range 1 is [0%, N1], the power range 2 is [N1, N2], the power range 3 is [N3, N4], the power range 4 is [N4, N5], and the power range 5 is [N5, 100%], that is, in FIG. 4, the minimum power amount that the terminal device 100 can support is an example of the actual minimum power amount 0% of the terminal device 100. As can be seen from FIG. 4, the application associated with the power range 1 is the application 1, the application associated with the power range 2 is the application 1 and the application 2, and the application associated with the power range 3 is the application 1, the application Program 2 and application 3, the applications associated with the power range 4 are the application 1, the application 2, the application 3, and the application 4. The applications associated with the power range 5 are the application 1, the application 2, and the application. Program 3, Application 4, and Application 5. For example, if the current remaining power of the terminal device 100 is in the range of [0%, N1], only the application 1 can be called, and the application 2 cannot be directly called.

Figure 4 is an example of associating a direct power range with an application. In an actual application, the power range can also be associated with an application type. See Table 1 for an example of another association:

Table 1

In the first embodiment, the terminal device 100 divides the power of the terminal device 100 into five power ranges, wherein the minimum power level included in the five power ranges is the minimum safe power of the terminal device 100, for example, 15%. The maximum amount of power included in the power range is the maximum power supported by the terminal device 100, that is, 100%. The terminal device 100 may first divide the application installed in the terminal device 100 into Different types, Table 1 is exemplified by dividing an application installed in the terminal device into four types, namely, a game application, a information push application, a communication application, and an audio application. And the application of the video application, of course, in the actual application, the application installed in the terminal device 100 can be divided into more or less types, which are not limited in the embodiment of the present invention. After the applications installed in the terminal device 100 are divided into different types, the power range is associated with the type of the application, for example, [30%, 50%) is associated with the communication application. The application participating in the power range herein may be all applications in the terminal device 100, that is, each application installed in the terminal device 100 is associated with a power range, or is associated with a power range. The application is only a part of the application installed in the terminal device 100, for example, the user sets some applications to be associated with the power range, and the other applications can be used normally by the user under any circumstances. Then, if each application installed in the terminal device 100 is associated with a power range, for example, the power of the terminal device 100 is within the range of [30%, 50%), all communication applications installed in the terminal device 100 Both are available applications associated with the range of power to which the current remaining power of the terminal device 100 belongs, such as a call application and a short message application. And if the application associated with the power range is only a part of the applications installed in the terminal device 100, for example, the power of the terminal device 100 is in the range of [30%, 50%), all the communication applications installed in the terminal device 100 The program or part of the communication type application is an available application associated with the power range to which the current remaining power of the terminal device 100 belongs.

In addition, because communication applications are generally more important, such as call-based applications, even if the remaining power is already relatively small, you can continue to support communications applications, to avoid users missing important calls or unable to make calls.

The processing of the first operation by the terminal device 100 will be described below. The processor 190 referred to herein does not invoke the first application and may include several methods:

Mode 1, the processor 190 does not directly call the first application, and the user's experience is that although the operation for calling the first application is performed, the terminal device 100 does not respond.

In mode 2, the processor 190 first outputs a prompt message to prompt the user, and the user determines whether to continue to invoke the first application. For example, the prompt information is text information, and the text information is “current residual power” The quantity may not meet the requirements of the first application, whether to continue to call, and the user can make a selection by operating the terminal device 100 after seeing the prompt information, and the terminal device 100 determines how to operate according to the user's selection. If it is determined that the call is abandoned, the terminal device 100 no longer processes, that is, does not call the first application. If the user chooses to continue the call, the processor 190 continues to call the first application in response to the user's operation, after all, the user experience is still the most important.

As to whether the processor 190 adopts the above method, it can be set in advance by the terminal device 100 or selected by the user in advance.

In a possible implementation, if the first operation is an operation performed by the user, if the first application requested by the first operation is not an available application associated with the power range to which the current remaining power of the terminal device 100 belongs, The terminal device 100 does not directly invoke the first application in the manner of the mode 1, and the processing may be somewhat straightforward. In order to provide a better user experience, the processor 190 can distinguish whether the first operation is an operation performed by the user or an operation performed by the application in the terminal device 100 after receiving the first operation, if the first operation is not performed by the user. In operation, if the first application requested by the first operation is not an available application associated with the power range to which the current remaining power of the terminal device 100 belongs, the processor 190 may directly not invoke the first application in the manner of the mode 1. program. However, if the first operation is an operation performed by the user, if the first application requested to be called by the first operation is not an available application associated with the power range to which the current remaining power of the terminal device 100 belongs, the processor 190 may follow the manner. The method of 2, that is, does not directly refuse to invoke the first application, but outputs prompt information. Hereinafter, the prompt information is referred to as first prompt information, and the first prompt information is used to prompt whether to abandon the first application. For example, the processor 190 may output the first prompt information through the display unit 140, or output the first prompt information or the like through the speaker 161, and the user may receive the first prompt information. For example, the processor 190 outputs the first prompt information through the display unit 140. The content of the first prompt information is “the current remaining power may not meet the requirement of the first application, is the call continued?”, and the first prompt information further includes two The options are "yes" and "no", see Figure 5. After receiving the first prompt information, the user may select according to the first prompt information, and feed back the selection result to the terminal device 100. For example, the user feeds back the selection result to the terminal device 100 by operating on the touch screen 131. The result of the selection of the user feedback includes two types: if the user selects "No", it is determined to give up calling the first application, or if the user selects "Yes", it is determined to continue to call the first application. Then, the processor 190 receives the selection result fed back by the user, and operates according to the selection result fed back by the user. When the result of the selection by the user feedback indicates that the first application is aborted, the processor 190 does not call the first application. When the result of the selection by the user indicates that the first application is continuously called, the processor 190 continues to call the first application. This can better meet the needs of users and improve the user experience. Moreover, since the first prompt information is output, the user already knows that the current power is not suitable for running the first application, and even if the user chooses to continue to call the first application, the user will be considered as much as possible when running the first application. In the case of power saving, or possibly charging the terminal device 100, the endurance capability of the terminal device 100 is improved.

In addition, since the power range has been divided, and different power ranges may be associated with different applications, if the remaining power of the terminal device 100 enters another power range from one power range, the terminal device 100 operates. The app may also have applications associated with the last battery range, and these apps may not already be associated with the current battery range in which the remaining battery is located, so if you continue to run these apps, it may not be good for Power saving. For example, if the remaining power of the terminal device 100 enters the second power range from the first power range included in the association relationship, the processor 190 may determine whether the currently running application in the terminal device 100 is not associated with the second power range. An application, if the processor 190 determines that the second application in the running application in the terminal device 100 is not an available application associated with the second power range, then one way is that the processor 190 directly closes the second application, In order to achieve the goal of power saving as quickly as possible, or in order to give the user a more friendly experience, the processor 190 may not directly close the second application, but select output prompt information, which is hereinafter referred to as second. The prompt information, the second prompt information is used to prompt whether to close the second application. For example, the processor 190 may output the second prompt information through the display unit 140, or output the second prompt information or the like through the speaker 161, and the user may receive the second prompt information. For example, the processor 190 outputs the first prompt information through the display unit 140. The content of the first prompt information is “the current remaining power is not suitable for running the second application, is the second application closed?”, and the second prompt The information also includes two options, "Yes" and "No", see Figure 6. After receiving the second prompt information, the user may select according to the second prompt information, and feed back the selection result to the terminal device 100. For example, the user feeds back the selection result to the terminal device 100 by performing an operation on the touch screen 131, and the selection result of the user feedback includes: Two kinds: If the user selects "Yes", it is determined to close the second application, or if the user selects "No", it is determined to continue to run the second application. Then, the processor 190 receives the selection result fed back by the user, and operates according to the selection result fed back by the user. When the selection result fed back by the user indicates that the second application is closed, the processor 190 closes the running second application, and when the selection result fed back by the user indicates that the second application continues to be run, the processor 190 does not operate. , keep the second application running normally. This can better meet the needs of users and improve the user experience. Moreover, since the second prompt information is output, the user already knows that the current power is not suitable for running the second application, and even if the user chooses to continue running the first application, the user will try to consider when running the second application. In the case of power saving, or possibly charging the terminal device 100, the endurance capability of the terminal device 100 is improved.

Referring to FIG. 7, an embodiment of the present invention provides a power management method, which may be performed by the terminal device 100 in the embodiment shown in FIG. 1A or FIG. 1B.

Step 701: The terminal device 100 receives a second operation, where the second operation is used to update a system or an application installed in the terminal device 100.

Step 702: The terminal device 100 determines whether the terminal device 100 is in a charging state.

Step 703: When the terminal device 100 is not in the charging state, the terminal device 100 does not respond to the second operation.

For some operations, for example, an operation for updating a system installed in the terminal device 100, that is, a system update class operation, or an operation for updating an application installed in the terminal device 100, that is, an application update class operation, or for updating a terminal The operation of the firmware in device 100, i.e., the firmware update class operation, has some features, such as the fact that such operations are relatively power hungry, and it is possible that processor 190 can be responsive to such operations before responding to such operations. The amount of electricity. Of course, the amount of power required to get the response to this operation is not necessarily very accurate, as long as it can roughly estimate the amount of power needed to respond to the operation. For example, for some update class operations, including updating the app The operation of the program, or the operation of updating the system, or the operation of updating the firmware, etc., generally allows the processor 190 to know in advance the amount of power required to respond to such operations.

After the terminal device 100 receives the second operation, the processor 190 may determine whether the terminal device 100 is in a charging state. If the terminal device 100 is not in the charging state, the processor 190 may choose not to directly respond to the second operation. And if the terminal device 100 is in a charging state, the processor 190 can respond to the second operation. In general, the second operation may consume a relatively large amount of power, so it is selected to be in a state of charge as much as possible to avoid excessive power consumption in response to the second operation, which affects the normal use of the terminal device 100.

Alternatively, because the processor 190 can obtain the amount of power required to respond to the second operation, if the terminal device 100 is not in the charging state, the processor 190 can determine the remaining amount of power of the terminal device 100 and the amount of power required to respond to the second operation. Whether the difference is less than a preset threshold, that is, whether the remaining power of the terminal device 100 can still be greater than or equal to a preset threshold after the response to the second operation is completed. If the difference between the remaining power of the terminal device 100 and the amount of power required to perform the second operation is less than a preset threshold, the terminal device 100 does not respond to the second operation. And if the difference between the remaining power of the terminal device 100 and the power required to perform the second operation is greater than or equal to a preset threshold, the terminal device 100 may respond to the second operation.

The preset threshold here is the safe power value of the terminal device 100, and may be the actual minimum power supported by the terminal device 100, for example, 0%, or the alarm power of the terminal device 100, for example, 20%, or 15%, and the like. If the preset threshold is the actual minimum power supported by the terminal device 100, the second operation that the terminal device 100 can respond in the non-charging state may be slightly more, because even if the remaining power of the terminal device 100 is less than the alarm power, the terminal device 100 is also It can work, so the preset threshold can be made the actual minimum power supported by the terminal device 100, so as to respond to more second operations as much as possible. In addition, the difference between the remaining power of the terminal device 100 and the power required to respond to the second operation cannot be made smaller than the actual minimum power supported by the terminal device 100, and also to prevent the terminal device 100 from being unresponsive to the second operation. Shutdown may cause disorder of the system or application in the terminal device 100. If the preset threshold is the alarm power of the terminal device 100, it can be guaranteed that the second operation does not affect the normal use of the terminal device 100.

The technical solution provided by the embodiment of the present invention can better reduce power consumption by using a customized rule to "block" or prompt before the application program starts to consume a large amount of power. Adopting the method of pre-constrained, combined with the user's own "customization" and participation, while achieving the power-saving effect, it also protects the user experience as much as possible.
